The ZyAIR uses an external power adapter with the following specifications.
Input: 100-240 VAC, 50/60 Hz, 0.4 A
Output: 5 V, 2 A

Power over Ethernet

The ZyAIR is compatible with IEEE 802.3af so it can receive power through an Ethernet cable. Use
standard 8-wire CAT 5 10/100 BaseT Ethernet cable to connect an IEEE 802.3af compatible power
injector to the WAN port.
The ZyAIR receives DC power through the unused twisted-wires (pairs 4/5 and 7/8) of the Ethernet
cable.
RJ-45 Ethernet Port
The following table describes the types of network cable used for the different connection speeds.
Make sure the Ethernet cable length between connections does
not exceed 100 meters (328 feet).
